[0017] The elevator according to the first embodiment further includes a rail device 13. The rail device 13 is provided on the landing jamb 12. The landing screen door 6 is movable along the rail device 13.

[0018] Specifically, the rail device 13 has a pair of rails 131. The pair of rails 131 are provided on each of a pair of vertical posts 122 in the landing jamb 12. The pair of rails 131 are arranged along the pair of vertical posts 122. The landing screen door 6 moves along the pair of rails 131. Therefore, the landing screen door 6 moves along the pair of vertical posts 122.

[0019] The screen door drive device 7 is provided on the landing jamb 12. Specifically, the screen door drive device 7 is provided inside the upper frame 123 of the landing jamb 12. A through hole 124 through which the landing screen door 6 passes is formed on the surface of the upper frame 123 facing the floor surface of the landing 11.

[0020] As the screen door drive device 7 is driven, the landing screen door 6 moves through the through hole 124. Specifically, as the screen door drive device 7 is driven, the landing screen door 6 is wound up by the screen door drive device 7, or the landing screen door 6 is sent out from the screen door drive device 7.

[0021] As the screen door drive device 7 is driven, the landing screen door 6 moves between the screen door installation position and the screen door storage position. When the landing screen door 6 is in the screen door installation position, the landing screen door 6 is arranged over the entire area of ​​the landing entrance / exit 121. On the other hand, when the landing screen door 6 is in the screen door storage position, the landing screen door 6 is arranged outside the entire area of ​​the landing entrance / exit 121. When the landing screen door 6 is in the screen door storage position, the landing screen door 6 is arranged inside the upper frame 123 of the landing jamb 12. Figures 4 and 5 show the landing screen door 6 in the screen door installation position.

[0022] The elevator according to the first embodiment is equipped with a plurality of hall button devices 14. Fig. 4 shows one of the plurality of hall button devices 14. The plurality of hall button devices 14 are provided at each of the halls 11 on each floor.

[0023] Fig. 8 is a block diagram showing an elevator according to embodiment 1. The hoisting machine 4, the car door driving device 103, the screen door driving device 7, and the hall button device 14 are each electrically connected to the elevator control panel 8. The elevator control panel 8 controls the driving of the hoisting machine 4, the driving of the car door driving device 103, and the driving of the screen door driving device 7.

[0024] The elevator control panel 8 controls the drive of the hoist 4, and thereby controls the movement of the car 1. The elevator control panel 8 controls the drive of the car door drive device 103, and thereby controls the movement of the landing door 5. The elevator control panel 8 controls the drive of the screen door drive device 7, and thereby controls the movement of the landing screen door 6.

[0025] Next, an operation of the elevator in which the inside of the car 1 is ventilated will be described. Fig. 9 is a flowchart showing the elevator ventilation method according to the embodiment 1. First, in step S101, an elevator non-use determination step is performed.

[0026] The elevator control panel 8 has a preset time T used in the elevator non-use determination process. Any value can be set for the time T. In the elevator non-use determination process, the elevator control panel 8 determines whether the elevator has not been used for more than the time T. In other words, the elevator control panel 8 determines whether the time T has elapsed since the elevator was last used. If the elevator control panel 8 determines in step S101 that the time T has not elapsed since the elevator was last used, the processing of step S101 is repeated.

[0027] On the other hand, if the elevator control panel 8 determines in step S101 that the elevator has not been used for more than the time T, the operation mode of the elevator transitions from the normal operation mode to the door-open standby mode. In the door-open standby mode, first, in step S102, a landing screen door installation process is performed.

[0028] In the landing screen door installation process, the elevator control panel 8 moves the landing door 5 from the landing door closed position to the landing door open position, and moves the landing screen door 6 from the screen door stored position to the screen door installed position, by moving the car door 102. In the landing screen door installation process, the landing screen door 6 is moved first, and then the landing door 5 is moved. Note that in the landing screen door installation process, the landing screen door 6 and the landing door 5 may be moved simultaneously.

[0029] When the car 1 is at a floor other than the preset floor, the elevator control panel 8 first moves the car 1 to the preset floor. After that, the elevator control panel 8 moves the car door 102 to move the landing door 5 from the landing door closed position to the landing door open position, and moves the landing screen door 6 from the screen door stored position to the screen door installed position. In this case, the landing screen door 6 may be moved from the screen door stored position to the screen door installed position at the same timing as when the car 1 is moved to the preset floor, and then the landing door 5 may be moved from the landing door closed position to the landing door open position.

[0030] After step S102, in step S103, a hall button operation determination step is performed. In the hall button operation determination step, the elevator control panel 8 determines whether or not the hall button device 14 has been operated. In step S103, if the elevator control panel 8 determines that the hall button device 14 has not been operated, the process of step S103 is repeated.

[0031] On the other hand, if the elevator control panel 8 determines in step S103 that the hall button device 14 has been operated, the operation mode of the elevator is shifted from the door-open standby mode to the normal operation mode. In the normal operation mode, first, in step S104, a hall screen storage process is performed.

[0032] In the landing screen door storage process, the elevator control panel 8 moves the landing screen door 6 from the screen door installation position to the screen door storage position.

[0033] In the landing screen door storage process, if the floor of the landing 11 where the operated landing button device 14 is located and the floor of the landing 11 where the landing screen door 6 is in the screen door installation position are the same floor, the elevator control panel 8 keeps the position of the landing door 5 in the landing door open position.

[0034] In the landing screen door storage process, when the floor where the operated landing button device 14 is located and the floor where the landing screen door 6 is in the screen door installation position are different floors, the elevator control panel 8 moves the landing door 5 from the landing door open position to the landing door closed position, and moves the landing screen door 6 from the screen door installation position to the screen door storage position. In this case, in the landing screen door storage process, the landing door 5 is moved first, and the landing screen door 6 is moved later. Note that in the landing screen door storage process, the movement of the landing door 5 and the movement of the landing screen door 6 may be performed simultaneously.

[0035] This completes the operation of the elevator, which ventilates the inside of car 1.

[0036] As described above, the elevator according to the first embodiment includes a car 1 having a car door 102, a landing door 5, a landing screen door 6, and an elevator control panel 8. The landing door 5 moves between a landing door closed position and a landing door open position. The landing screen door 6 moves between a screen installation position and a screen door stored position. When the elevator has not been used for more than a time T, the elevator control panel 8 moves the car door 102 to move the landing door 5 from the landing door closed position to the landing door open position, and moves the landing screen door 6 from the screen door stored position to the screen door installation position. According to this configuration, the landing door 5 moves from the landing door closed position to the landing door open position, ventilating the inside of the car 1, and the landing screen door 6 moves from the screen door stored position to the screen door installed position, preventing foreign objects from entering the inside of the car 1 through the car entrance 104. Therefore, it is possible to prevent foreign objects from entering the inside of the car 1 through the car entrance 104 while the inside of the car 1 is being ventilated.

[0037] The elevator according to the first embodiment also includes a rail device 13 provided on the landing jamb 12 in which the landing entrance / exit 121 is formed. The landing screen door 6 moves along the rail device 13, thereby causing the landing screen door 6 to move between the screen installation position and the screen release position. This simple configuration allows the landing screen door 6 to move between the screen installation position and the screen release position.

[0038] The elevator according to the first embodiment also includes a landing button device 14 provided at the landing. When the landing button device 14 is operated with the landing door 5 in the landing door open position and the landing screen door 6 in the screen installation position, the elevator control panel 8 moves the landing screen door 6 from the screen installation position to the screen storage position. According to this configuration, when an elevator user operates the landing button device 14, the landing screen door 6 moves from the screen installation position to the screen storage position. This allows the user to use the elevator freely.

[0039] Moreover, in the elevator according to the first embodiment, the landing screen door 6 is provided only on a preset floor among the multiple floors. When the car 1 is at a floor other than the preset floor and the elevator has not been used for more than the time T, the elevator control panel 8 moves the car 1 to the preset floor and moves the car door 102 to move the landing door 5 from the landing door closed position to the landing door open position, and moves the landing screen door 6 from the screen door storage position to the screen door installation position. According to this configuration, there is no need to provide the landing screen door 6 on floors other than the preset floor among the multiple floors. This makes it possible to reduce the number of landing screen doors 6.

[0040] The elevator ventilation method according to the first embodiment also includes a landing screen door installation step. The landing screen door installation step is performed when the elevator has not been used for more than the time T. In the landing screen door installation step, the elevator control panel 8 moves the car door 102 to move the landing door 5 from the landing door closed position to the landing door open position, and moves the landing screen door 6 from the screen door storage position to the screen door installation position. According to this configuration, the landing door 5 moves from the landing door closed position to the landing door open position, ventilating the inside of the car 1, and the landing screen door 6 moves from the screen door storage position to the screen door installation position, suppressing foreign objects from entering the inside of the car 1 through the car entrance 104. Therefore, it is possible to suppress foreign objects from entering the inside of the car 1 through the car entrance 104 while the inside of the car 1 is being ventilated.

[0041] The elevator ventilation method according to the first embodiment also includes a landing screen storage step. The landing screen storage step is performed after the landing screen installation step. In the landing screen storage step, when the landing button device 14 provided at the landing 11 is operated, the elevator control panel 8 moves the landing screen 6 from the screen installation position to the screen storage position. According to this configuration, when an elevator user operates the landing button device 14, the landing screen 6 moves from the screen installation position to the screen storage position. This allows the user to use the elevator freely.

[0042] In the elevator according to the above-mentioned first embodiment, the car 1 has been described as including the car body 101, the car door 102, and the car door drive device 103. The car 1 may be configured to include a fan in addition to the car body 101, the car door 102, and the car door drive device 103. In this configuration, when the elevator has not been used for more than the time T, the elevator control panel 8 moves the landing door 5 from the landing door closed position to the landing door open position, moves the landing screen door 6 from the screen door retracted position to the screen door installed position, and further drives the fan so that the air inside the car 1 flows toward the landing 11. This makes it possible to suppress adhesion of foreign matter to the landing screen door 6.

[0043] Furthermore, in the elevator according to the above-mentioned first embodiment, the car 1 has been described as including the car body 101, the car door 102, and the car door drive device 103. The car 1 may be configured to include an in-car lighting device in addition to the car body 101, the car door 102, and the car door drive device 103. In the case of this configuration, when the elevator has not been used for more than the time T, the elevator control panel 8 moves the landing door 5 from the landing door closed position to the landing door open position, moves the landing screen 6 from the screen storage position to the screen installation position, and further turns off the in-car lighting device.

[0044] In the elevator according to the above-mentioned first embodiment, the car 1 has been described as including the car body 101, the car door 102, and the car door drive device 103. The car 1 may be configured to include an in-car speaker device in addition to the car body 101, the car door 102, and the car door drive device 103. In this configuration, when the elevator has not been used for more than the time T, the elevator control panel 8 moves the landing door 5 from the landing door closed position to the landing door open position and moves the landing screen door 6 from the screen door stored position to the screen door installed position, and further, the in-car speaker device notifies the user that the landing screen door 6 has moved from the screen door stored position to the screen door installed position.

[0045] Furthermore, in the elevator according to the above-mentioned first embodiment, a configuration has been described in which the pair of rails 131 are arranged along the pair of vertical pillars 122. A configuration in which the pair of rails 131 are arranged along the frontage direction of the landing entrance 121 may also be used. In this configuration, the landing screen door 6 moves in the frontage direction of the landing entrance 121.
